Earlier this week, one iPhone Dev-Team member teased a new version of Redsn0w that would allow users to downgrade their A5-powered devices — including the iPhone 4S, the iPad, and the new iPad — to iOS 5.0.1 and above for jailbreaking.

Feel free to upgrade your A4 devices to iOS 5.1.1 without losing the ability to jailbreak.

We’d usually advise jailbreakers to avoid Apple’s iOS updates just after their release, until hackers have confirmed that the latest software can be jailbroken. But one report claims that it’s perfectly safe to update your A4-powered devices to iOS 5.1.1 without losing your Redsn0w jailbreak.

Just hours after its release on March 16, Apple’s new iPad was jailbroken by the iPhone Dev-Team. Their announcement gave us hope that an exploit for A5 and A5X devices running iOS 5.1 would be available within weeks, but it now seems like we’ll be waiting a whole lot longer than that.
